Your robots batteries have a capacity of 1500mA*hour. When the robot moves forward, its motors consume 600mA. The forward speed of the robot is 0.5 feet/second. There are 3 feet in a yard. There are 3600 seconds in an hour. Assume the motors will run until the last coulomb of charge has been consumed. How many yards will the robot travel before it stops?
